Detail
Screening of Microcystins in water samples at 0.1 ppb (drinking water)
Attogene’s Microcystin Test Kit (Rapid – Drinking Water) can be used to detect microcystins in water to as low as 0.1ppb; highly sensitive, rapid, robust screening kit for microcystins and nodularins.
The most frequently reported cyanobacterial toxins are the hepatotoxic microcystins (MCs). MCs are peptides with a molecular weight ranging from 900 to 1,100 Da. They consist of seven amino acids of which the two terminal amino acids of the linear peptide are condensed to form a cyclic compound.
A tiered notification system which takes different actions based on thresholds for microcytin-LR concentrations in drinking waters has been developed. This is guidance that allows states to take various actions.
For the rapid screening of microcystins in drinking water samples at or above 0.1 ppb. Samples requiring regulatory action should be confirmed by ELISA, HPLC, or other conventional methods.
To protect consumers from adverse health effects caused by these toxins, the World Health Organization (WHO) has proposed a provisional upper limit for Microcystin-LR of 1.0 ppb (μg/L) in drinking water.
The U.S. Environmental Protection Agency (EPA) has also established guidelines for Microcystins in drinking water:
-For children below school age, 0.3 μg/L (ppb)
-For all other age groups, 1.6 μg/L (ppb)

AAV Purification from any input – cell fraction or media fraction
High AAV recovery, up to 90%
No specialized equipment needed
Purification from a variety of AAV serotypes (including AAV6 and AAV9)
Yields highly active AAV for in vivo and in vitro experiments
Purification is based on spin column chromatography that uses Norgen’s resin separation matrix
Recombinant adeno-associated virus (AAV) vectors are highly promising tools for both in vitro and in vivo gene transfer. Norgen’s AAV Purification Kits provide fast and simple procedures for concentrating and purifying AAV vectors from cell lysate and cell culture media. Purification is based on precipitation onto Norgen Biotek’s proprietary resin. Contaminating cellular debris is largely removed from the sample via a centrifugation step, while contaminating DNA and RNA is reduced using enzymatic digestion. AAV vector purified in this manner is highly active for use in in vitro and in vivo transduction experiments.
AAV Purification Kit
Norgen’s AAV Purification Kit contains sufficient materials for 15 preparations (33.5 mL per prep of supernatant (SN) or a total of 500 mL of supernatant input). Approximately 1 mL of cell pellet can be purified per prep, up to a maximum of 15 mL of cell pellet in total for the entire kit. Up to 33X sample concentration.
AAV Purification Mini Kit
Each spin column is able to concentrate and purify AAV from 0.5-8 mL of cell pellet, cell culture media, or cells and culture media mixed together. Up to 50X sample concentration. AAV vector purified in this manner is highly active for use in in vitro transduction experiments, and is eluted into a small volume (200 µL). Preparation time for 4 samples is 1.5 hours, with 45 minutes of hands-on time.
AAV Purification Midi Kit
Each spin column is able to concentrate and purify AAV from 8 mL up to 45 mL of input consisting of cell pellet, cell culture media, or cells and culture media mixed together. Up to 50X sample concentration. AAV vector purified in this manner is highly active for use in in vitro transduction experiments, and is eluted into a small volume (1 mL). The kit may be used to purify up to 8 x 25 mL or 4 x 45 mL of samples using the included columns. Preparation time for 4 samples is approximately 2 to 2.5 hours, with 1.5 hours of hands on time.
AAV Purification Maxi Kit (Slurry Format)
Each spin column is able to concentrate and purify AAV from 45 mL to 90 mL of input consisting of cell pellet, cell culture media, or cells and culture media mixed together. Up to 200X sample concentration. AAV vector purified in this manner is highly active for use in in vitro transduction experiments, and is eluted into a small volume (1-10 mL) using the optional concentration step. The kit may be used to purify up to 1 x 900 mL samples or 10 x 45-90 mL samples using the included columns. Preparation time for 1 x 900 mL sample is approximately 2.5 to 3.5 hours, with an optional concentration step requiring an additional 30 min.

Magnetic bead nucleic acid purification technology uses nano or micron superparamagnetic material as the matrix, generally black ferric oxide or yellowish brown ferricoxide as the magnetic material. The surface of bead is coated with appropriate functional groups, which can adsorb nucleic acid. Magnetic beads commonly used for nucleic acids, containing carboxyl groups, hydroxyl groups, or silicon groups. Silicon-based magnetic beads are the most common, and its principle of adsorbing nucleic acid is consistent with the classical glass milk purification technology or glass fiber filter membrane purification method. Magpure particle is a kind of polydisperse fast speed silica magnetic beads. The core is ferricoxide, accounting for 50%, and the surface coating is silica, accounting for 50%. The product can be used for plasmid extraction, gel DNA recovery, product purification, genomic DNA and RNA extraction, and viral nucleic acid extraction.

Principle
Highsalt mediated binding: in the solution containing 2-4M guanidine isothiocyanate, Magpure particles can selectively recover DNA molecules, and impurities such as protein polysaccharides are not adsorbed.
Alcohol mediated binding: in the solution containing guanidine salt and alcohol (>25%), Magpure particles can selectively recover DNA/RNA molecules, and proteins and other impurities are not adsorbed.
After biological samples are treated with digestive solution or lysis Buffer, DNA/RNA is released from cells, organelles and protein complexes (ribosomes and nucleosomes) into reagents. After Magpure particles and binding solution are added, DNA/RNA is adsorbed to the surface of Magpure particles to form DNA/RNA bead complex. Under the action of the magnetic field, the magnetic beads are separated and collected, and the impurities such as protein are removed with the waste liquid. After two or three steps of further cleaning, the DNA/RNA magnetic bead complex is resuspended in sterilized water or TE buffer, and the DNA/RNA falls off from the surface of the magnetic beads, so as to achieve the purpose of purification.

The MagPure magnetic-particle technology combines the speed and efficiency of silica-based DNA purification with the convenient handling of magnetic particles. DNA binds to the silica surface of the magnetic particles in the presence of a chaotropic salt. DNA bound to the particles is then efficiently washed, considerably improving the purity of DNA. High-quality DNA is eluted. The automated purification procedure completely removes enzymes, nucleotides, and other contaminants and inhibitors. Purified DNA is suitable for direct use in downstream applications, such as sequencing and microarray analysis.
